2021 Fantasy Outlook
Jax, a 2016 third-round draft pick, pitched in just 40 minor league games from 2016 to 2019 as his ability to play minor league baseball was severely limited by Air Force obligations. While he's a bit old for a prospect (26 this season), he's shown promise at higher levels with a 2.67 ERA and 1.94 BB/9 at Double-A in 2019. He hasn't had great strikeout rates (6.7 K/9 in 2019), However. Still, he's still a bit of an unknown given his sparse minor league career. Minnesota should get a better picture with a full season in 2020. He could add rotation depth at Triple-A if all goes well. Read Past Outlooks

Finishes season on high note
PMinnesota Twins
October 3, 2021
Jax (4-5) earned the win over Kansas City on Saturday, pitching five shutout innings during which he allowed one hit and two walks while striking out three.
ANALYSIS
Jax put together an up-and-down rookie campaign, and he saved his best for last as Saturday's outing was his first in which he didn't allow a run. The right-hander surrendered just one hit -- a third-inning single -- and didn't allow any runners to reach second base. Jax finished his first big-league season with a 6.37 ERA, 1.35 WHIP and 65:29 K:BB across 82 innings. Moving forward, he'll need to do a better job of keeping the ball in the park to find sustained success, as his 2.52 HR/9 in 2021 ranks third-highest among pitchers who have thrown at least 50 innings.
